Title: Equipment for controlling sheet thickness
Inventor: YAMAMOTO YASUYUKI
IPC: B21B37/72
Filed: 1982-02-15
Abstract: PURPOSE:To control the increase of sheet thickness of a steel sheet caused by missing a tension out of the tail end of the sheet, to the prescribed thickness without reducing a roll gap, by controlling the heating temperature of the sheet to control the width of it at the time when the tail end passes through rolls, in hot rolling a steel sheet by plural sets of rolling stands. CONSTITUTION:In hot rolling a steel sheet 2 by a group 1 of plural rolling stands, the equivalent width and length of sheet at the inlet side of the mill are obtained by an arithmetic device 4. Next, the temperature of sheet 2 to be heated at each stand is calculated by an arithmetic device 5, and further, the length of tail end of the sheet 2 is measured to recognize the position of tail end by a position detecting device 6. These signals outputted from respective devices are inputted to a steel sheet heating device 7; and as the sheet 2 is heated by the device 7 at the timing and at the temperature to be heated, the thickness of tail end of the sheet 2 after passing through the final stand is controlled to the prescribed thickness without reducing the roll gap.

Title: Damper for stepping motor
Inventor: MORISHITA KEISUKE
IPC: H02K37/22
Filed: 1990-02-02
Abstract: PURPOSE:To rotate a rotary shaft smoothly by attaching a flywheel capably in sliding to the rotary shaft of a stepping motor, and attaching a vibration absorbing material to this flywheel. CONSTITUTION:An flywheel 32 is not fixed firmly to the rotary shaft 11 of a stepping motor, but the out in contact with the rotary shaft through a fixed part 22 is vibration absorbing material 37, so the flywheel itself 32 is attached in a slidable state. The flywheel 32 does not rotate quite the same as the rotation of the rotary shaft 11 of the stepping motor. For that reason, the flywheel 32 does not have the pulsatile operation similar to the rotary shaft 11 of the stepping motor 11, but tends to rotate smoothly by its inertia.

Abstract: PURPOSE:To form the layer of a metal outer than Al and Si on an Al alloy contg. Si with satisfactory adhesion by immersing the Al alloy in a soln. contg. fluorine ions, bringing a metallic halide into contact with the alloy and heating the alloy to a proper temp. CONSTITUTION:An Al alloy contg. Si is immersed in a soln. contg. fluorine ions such as hydrofluoric acid to lower the concn. of Si on the surface of the alloy. A metallic halide such as cuprous chloride is applied to the alloy with a binder or the like. The alloy is then heated to a temp. at which a substitution reaction takes place between the metallic halide and Al and is below the m.p. of the alloy to coat perfectly the surface of the alloy with different kind of metal such as copper. Since the resulting coating is formed on the alloy with a uniform mutual diffusion layer in-between, it has satisfactory adhesion.

Title: Rush current limiting circuit for power source
Inventor: MIZUNO SUMINORI
IPC: H02M7/06
Filed: 1978-03-08
Abstract: PURPOSE: To limit a rush current, by controlling the turn-on phase of a power switch element by the charged voltage of a smoothing capacitor and advancing the phase stepwise and raising the charged voltage of the smoothing capacitor.  
     CONSTITUTION: AC power 1 is rectified to charge the smoothing capacitor 3  through a triac 7 to energize a load 4. When interlocked switches 5, 5' are closed, a capacitor 39 is charged through the smoothing capacitor 3 while the peak value of the sine waves of the AC power 1 is higher than the Zener voltage of a Zener diode 39. When the peak value is lower than the Zener diode, the charging is stopped and the capacitor 39 is discharged to supply a trigger current to the triac 7. Because the peak value of the sine waves at the time of starting discharging the capacitor 36 is controlled by the charged voltage of the smoothing capacitor 3, a current controlled to be stepwise is applied to the smoothing capacitor 3. Thus, an excessive rush current is prevented.
